We first sought to clarify the effects of discounted rate, survival rate, and lactation persistency as a component trait of the selection index on net merit, defined as the first five lactation milks and herd life (HL) weighted by 1 and 0.389 (currently used in Japan), respectively, in units of genetic standard deviation. Survival rate increased the relative economic importance of later lactati...

A study was conducted in Malaysia of 148 women seeking induced abortion from doctors. The influence of socioeconomic, ethnic, religious, and educational factors on the practice of induced abortion in Malaysia was examined along with the relationship of induced abortion to the use of contraceptives. 135 of the women were married; 13 were unmarried. 22.3% of the women did not complete primary ...

Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...

background: mccune albright syndrome is rare with an estimated prevalence of 1 in 100,000 to 1 in 1,000,000 persons. the classical clinical triad consists of fibrous dysplasia of the bone, café-au-lait skin spots and precocious puberty. however, in rare cases, there may be primary hypogonadism and amenorrhea. case presentation: an eighteen-year-old female presented with amenorrhea. she had a sh...

Random regression models (RRM) are used for genetic estimations of milk traits in dairy cows. RRM utilize data on traits that are repeated during the time, such as milk trait, which allows of the evaluation of the test day production information. In this study, to estimate genetic parameters for milk production trait, test day records (TDR) were collected from the first lactation of Holstein co...

The study aimed to determine factors affecting the dry period length and effect of dry days on milk yield, milk composition and lactation length in the next lactation of dairy cows. Data used for analysis included 7264 lactation records collected from 2012 to 2016 on 4737 Holstein cows raised in 152 herds. The statistical model used to determine the factors influencing the dry period length sho...

A case of X;9 balanced translocation in a female with amenorrhoea is reported. The X breakpoint was at Xq21, inside the 'critical region'. The normal X was consistently late replicating in blood lymphocytes and skin and ovary fibroblasts.

Records for daily feed intake during lactation were available for 774 sows with 2,234 litters farrowing from May 2002 to November 2006. Genetic parameters were estimated for whole-oflactation feed intake and feed intake averaged over 5-day periods during lactation. Estimates of heritabilities and the permanent environment of the sow were 0.16±0.05 and 0.18±0.04 for total lactation feed intake a...
